Function File: sys = d2c (sys)

Function File: sys = d2c (sys, method)

Function File: sys = d2c (sys, 'prewarp', w0)

Convert the discrete LTI model into its continuous-time equivalent.

Inputs

sys

Discrete-time LTI model.

method

Optional conversion method. If not specified, default method "zoh" is taken.

’zoh’

Zero-order hold or matrix logarithm.

’tustin’, ’bilin’

Bilinear transformation or Tustin approximation.

’prewarp’

Bilinear transformation with pre-warping at frequency w0.

’matched’

Matched pole/zero method.

Outputs

sys

Continuous-time LTI model.
